What is the working principle of the oil pressure tensioner
The working principle of oil pressure tensioner is to provide dynamic adjustment guarantee for timing belt or chain through precise design of oil pressure mechanism.
The main function of the oil pressure tensioner is to ensure that the timing system is always in the best condition to protect the smooth operation of the engine. Its working principle is based on an internal oil pressure mechanism, which adjusts the timing belt or chain through a hydraulic system to ensure that they remain in optimal working condition. Specifically, when the engine starts, the rotation of the crankshaft will drive the pulley to rotate, and then transfer power to the generator, air conditioning compressor and other accessories through the belt. In this process, the oil pressure tensioner automatically adjusts the tension of the belt through its internal hydraulic system, ensuring that the belt is always in optimal working condition. The oil pressure tensioner contains a rotating tensioner arm, which is connected to the tensioner body by a hydraulic system. When the belt is relaxed due to long-term use, the hydraulic system will drive the tightening arm to move outward, thereby increasing the tension of the belt; Conversely, when the belt becomes too tight due to a new replacement or temperature change, the hydraulic system drives the tightening arm inward, reducing the tension on the belt. In addition, the oil pressure extender is equipped with a hydraulic damping system, which absorbs the vibration generated by the belt during operation, thereby reducing noise and extending the service life of the belt. The hydraulic damping system achieves this function through the internal flow of oil, which provides smooth resistance as the tightening arm moves, ensuring smooth and impact-free belt tension adjustment.
The main causes of oil leakage in tensioner include:
Seal ring damaged : there is a set of bearings with a seal ring inside the tensioner. If the seal ring is damaged, oil will leak.
bearing lack of lubricating oil : bearing parts may leak oil due to lack of lubricating oil.
Coping measures
Once it is found that the tensioner is leaking oil, the following measures should be taken as soon as possible:
Replace tensioner : Since oil seepage means that the seal ring or bearing may have been damaged, it is recommended to replace the tensioner as soon as possible to avoid a more serious failure.
professional maintenance : the vehicle will be sent to a professional maintenance site for detailed inspection and repair to ensure the normal operation of all parts.
